LM393AD datasheet by Texas Instruments

LM393AD Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM393AD?
  The maximum input voltage that can be applied to the LM393AD is 36V, but it's recommended to keep it below 30V to ensure reliable operation.
• Can I use the LM393AD as an amplifier?
  No, the LM393AD is a comparator, not an amplifier. It's designed to compare two input voltages and output a digital signal, not to amplify a signal.
• How do I choose the right pull-up resistor value for the output?
  The pull-up resistor value depends on the output current required and the voltage supply. A good starting point is a 1kΩ to 10kΩ resistor, but you may need to adjust it based on your specific application.
• What is the response time of the LM393AD?
  The response time of the LM393AD is typically around 1.3μs, but it can vary depending on the input voltage and output load.
• Can I use the LM393AD with a single supply voltage?
  Yes, the LM393AD can be used with a single supply voltage, but you'll need to ensure that the input voltages are within the common-mode range of the device.
